Title: Valve timing adjusting device
Inventor: KUSANO SHIGEYUKI
IPC: F01L1/344
Filed: 2003-11-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a valve timing adjusting device preventing wear of a member constructing a restriction means in a predetermined angle position at which a restriction member can restricts relative rotation of a drive side rotary member and a driven side rotary member.  <P>SOLUTION: The most advanced angle position at which a stopper piston 32 fits in a fitting ring 36 is a target phase. When difference between actual phase and the target phase is small, working fluid is supplied to each retarding hydraulic chamber and each advancing hydraulic chamber and working fluid is also supplied to a first pressure chamber 40 and a second pressure chamber 42. Consequently, a stop piston 32 does not project in a fitting ring 36 side. When a vane rotor 16 reaches the target phase, control is executed to discharge working fluid from the each retarding hydraulic chamber and the first pressure chamber 40. Since force acting on the stopper piston 32 from the second pressure chamber 42 is small when pressure of working fluid is predetermined pressure or less, the stopper ring 32 fits in the fitting ring 36.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
